'Normally, the thing I do the best is hit it short and straight, but today I had two lost balls in the bushes,' said Bogan. 'I was pretty happy with 71 after giving four strokes away.'

Bill Zylstra, whose first-round 65 was a record for this event, struggled to a 2-over 73 in round two. He shared second at minus-4 with Paul Simson, a co-medalist at both the 2004 U.S. Mid-Amateur and last year's USGA Senior Amateur.

'With match-play events, you've got to play well, and if you have somebody playing well against you, you've got to play a little bit better,' said Simson. 'That's just the nature of the beast.'
